cocoapod是GoogleMobileAd framework推荐的一个自动解决依赖关系的工具。

 

安装cocoapod时遇到问题：

EthandeMacBook-Air:Xcode ethan$ sudo gem install cocoapods

ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:

          Unable to download data from https://rubygems.org/ - Errno::ECONNRESET: Connection reset by peer - SSL_connect (https://rubygems.org/latest_specs.4.8.gz)

 

在google上搜了一堆歪果仁的答案，都没什么卵用。 

解决方案： 这是由中国特色GFW导致的故障，将gem源换掉即可：

 

EthandeMacBook-Air:Xcode ethan$ gem sources --remove https://rubygems.org/

https://rubygems.org/ removed from sources

EthandeMacBook-Air:Xcode ethan$ gem sources -a https://ruby.taobao.org/

https://ruby.taobao.org/ added to sources

 

理论上讲

 

找不到命令pod，运行which pod没有反应，由于权限引起，

sudo chmod 755 /usr/local/bin
